ユニセックス グレー クルー スポーツソックス - 82440 - 1足（個別袋入り・ハンガー掛け可能） 82440-00は12足入りバルクパック（個別包装なし）

The 10-13 sizing actually fits my big feet perfectly, which is rare for crew socks. I grabbed a single pair to test before committing to the bulk 12-pack, and the fact that they come individually bagged makes them easy to toss in a gym bag or gift.

The gray color goes with everything I own, and the crew height hits right at mid-calf without sliding down during my workouts. Bought a single pair first to test the 10-13 sizing, and the fit is snug but not tight on my size 10 feet.

Got these for my dad who wears a 12, and the 10-13 sizing fits him perfectly without any bunching at the toe. The crew height sits right at his calf and they're thick enough for his daily walks, though I do wish they came in a two-pack for the price.
